"The effects of various technical and economic parameters on LMFBR deployment plans have been studied to assess the best future mix of light water reactors and fast breeder reactors which will result in minimum cumulative nuclear generating costs discounted to the year 1985. Projected growth in domestic nuclear generating capacity was taken from various predictions [19, 20, 21], and the future domestic nuclear generating capacity was assumed to consist only of light water reactors and liquid metal cooled fast breeder reactors. Technical characteristics representing the two reactor types were taken as fixed, typical values for this study. The light water reactor characteristics represent a composite between PWRs and BWRs, whereas the most recent follow-on design was used as the reference for LMFBRs. Annual domestic power generation costs are calculated as a function of the installed capacity of both light water and fast breeder reactors in each particular year, the unit costs of each reactor type, the load factor, plutonium requirements, plutonium price and discount rate, and other factors. The cumulative nuclear generating costs are then computed as the sum of the discounted annual costs."
